   <span class="function"><strong>maxdb_stmt_bind_result()</strong></span> is used to associate (bind) columns in the result
   set to variables. When <span class="function"><a href="maxdb_stmt_fetch.html" class="function">maxdb_stmt_fetch()</a></span> is called to fetch data, the MaxDB
   client/server protocol places the data for the bound columns into the specified variables
   <code class="parameter">var1, ...</code>.
  </p>
  <blockquote class="note"><p><strong class="note">Note</strong>: 
   <p class="para">
    Note that all columns must be bound prior to calling <span class="function"><a href="maxdb_stmt_fetch.html" class="function">maxdb_stmt_fetch()</a></span>.
    Depending on column types bound variables can silently change to the corresponding PHP type.
   </p>
   <p class="para">
    A column can be bound or rebound at any time, even after a result set has been partially retrieved.
    The new binding takes effect the next time <span class="function"><a href="maxdb_stmt_fetch.html" class="function">maxdb_stmt_fetch()</a></span> is called.
